Important information
Only holder of a valid Interspiro Service Certificate for the equipment in
question may carry out service and repairs on Interspiro breathing equipment.
Unauthorized service may result in malfunction and users relying there on
could sustain severe respiratory injury or death.
Whenever the equipment has been dismantled and assembled, it´s operation
must be checked in accordance with the Interspiro test instructions. Failure to
conform to this requirement may result in equipment malfunctions and cause
serious injury or death.
Changes to this document – necessitated by typographical errors, inaccuracies
of current information or improvements and changes of equipment – may be
made at any time without prior notice. Always refer to www.interspiro.com for
product or document updates and for service bulletins.
The chapter "Important information" must be read completely and the
regulations described there must be followed when doing any kind of service,
tests or repair on the apparatus. Failure to comply to this instructions may lead
to serious damage to the equipment, serious injury or death.
WARNING
Pressurized systems must always be handled with caution. In
extreme cases, fractures can occur in high pressure parts
which can be a danger to life.
CAUTION
In a number of the function tests, blowing sounds will occur
which can damage hearing. Always use hearing protection.

7,5 bar (94 psi) pressure. Press in the Selector valve (12) to start the flow.
10. Not used.
11. Shutting-off screw with a outlet that gives a constant flow of 7 l/min at 2
bar (29 psi).
12. Selector valve press in to start the flow to the hose nipple (9) and
stopping the flow to the shutting-off screw (11).
13. Medium pressure connection to connect the breathing valve hose of the
regulator unit that is tested. Fitted with a safety valve that opens at 25 bar
(363 psi).
14. Needle valve
15. Secondary pressure gauge for reading the secondary pressure from the
tested pressure regulator.
16. Primary pressure gauge for reading the secondary pressure of the
pressure regulator (4).
17. Test adapter housing to connect the test adapter in.
18. Hose with cover for connection between the hose nipple and the test
adapter.
19. Adapter hose to connect between the 3-way adapter and the medium
pressure connection.
20. Test adapter Spiromatic to connect the breathing valve to the
measurement housing.
21. Adapter for connecting the breathing hose from the regulator unit to the
medium pressure connection.
22. Key for drag pointer to set the primary pressure gauge to zero.
23. 3-way adapter for testing breating valves.
The Spiromatic test is used to do performance tests of Interspiro breathing
apparatuses.
The Spiromatic test is mounted on a mounting plate in an aluminium transport
box. The mounting plate with the test equipment can be removed and secured
to the wall of the workspace if desired.
Remove the six screws to remove the plate.

Maintenance
If the Spiromatic test needs to be repaired, it has to be sent to Interspiro for
reparation.
The Spiromatic test must be sent to Interspiro for service and calibration every
year.
If the Spiromatic test has not been calibrated by Interspiro for over a year, it
must not be used.
Strikes and/or impacts can damage:
• unprotected threads - which can make it impossible to assemble parts
• plastic components - which will reduce the performace of the equipment
• hoses - which can cause the hose to fracture

Before use
The Spiromatic test must only be used with air from a cylinder or a distributed
high pressure network.
Only use breathing air according to EN 12021.
Preparation
Before doing any tests with the Spiromatic test it has to be prepared and it´s
fuctions tested.
1. Make sure that the pressure gauge is on zero. If needed, turn the adjusting
screw with a slotted screwdriver until it is.
2. Turn out the regulating screw until it feels loose (counterclockwise). Stop
before it falls out.

3. Make sure that the protective plug is mounted in the connecting piece.
4. Turn the shutting-off screw clockwise until it is closed. This will stop the
flow to the hose nipple.
5. Make sure that the needle valve is closed. If needed, turn clockwise until it
is closed.

6. Assemble the hose with cover.
7. Connect a pressure source of maximum 300 bar to the Spiromatic test.
Testing can proceed to a pressure of 100 bar.
8. Slowly open the air supply.
9. Turn the regulating screw in (clockwise) until the primary pressure gauge
shows 80 bar.
NOTE: If the pressure rises after the adjustment, open the needle valve
and close the air supply.
If this happens, the Spiromatic test is defect and must be repaired by
Interspiro.

10. Close the air supply and make sure that the air supply pressure gauge
does not show any decrease in pressure during 60 seconds.
If the pressure drops, the Spiromatic test is defect and must be repaired by
Interspiro.
11. Open the needle valve to vent the system.
12. Close the needle valve.
